"Contemplating is receiving." (St. John of the Cross) What we receive in prayer is the Spirit, who makes all creation new, moment by moment. It is the Spirit who rebirths us within the caves of our hearts. The case is a metaphor for this silent withdrawal, this going away to be alone, to listen, to gestate the Spirit, to rebirth ourselves. The reborn self is the child of wisdom born in solitude.
True service isn't an act, but an attitude. We can do things for other people with all kinds of self-serving motives. True service, however, stems from a feeling of humility, gratitude, and the essential recognition that we are in this together... Service is love in action -- as simple as a friendly smile or nod to a stranger -- or as all embracing as the life of Peace Pilgrim or Mother Teresa.
